this.resetFontSize=function (wordbox, maxHeight, minSize, maxSize) { 
    //  var wordbox = $(".products .title"); 
    //最大高度 
    //var maxHeight = 30; 
    //初始化文字大小为最小 
    wordbox.css('font-size', minSize + "px"); 
    maxSize++; 
    wordbox.each(function () { 
      //循环修改大小直至大于最大高度 
      for (var i = minSize; i < maxSize; i++) { 
        if ($(this).height() > maxHeight) { 
          //当容器高度大于最大高度的时候，上一个尝试的值就是最佳大小。 
          $(this).css(&#39;font-size&#39;, (i - 2) + &#39;px&#39;); 
          //结束循环 
          break; 
        } else { 
          //如果小于最大高度，文字大小加1继续尝试 
          $(this).css(&#39;font-size&#39;, i + &#39;px&#39;); 
        }
